The National Traffic Safety Committee has launched an investigation into a 25-year-old man who claims he rode his motorbike from HCM City to Hà Nội in less than 20 hours.

A Facebook account called Tô Hà Đông Nghi has been posting photos and information about this young man who allegedly covered the 1,700km in just 19 hours 45 minutes, including short breaks to eat and refuel.

"I am 25 years old, and have just completed my motorbike trip across the country. I was going at full speed and it took me 19 hours 45 minutes from HCM City to Hà Nội."

According to traffic experts, to make the trip from HCM City to Hà Nội in 20 hours, he would have needed to be travelling at an average speed of 85km/h.

For motorbike driver on Highway 1, the speed limit is 60km/h in densely populated areas, and 70km/h on open stretches.

Except for short breaks, traffic experts estimated he would have been driving at full speed regardless, and in doing so breaking the speed limit.

In a dispatch to the Traffic Police Department, the National Traffic Safety Committee said that if the story was true, Tô Hà Đông Nghi had seriously violated traffic regulations.

He could have caused a serious accident and should be strictly punished, it added.

So, there we have a case of the fast and the furious! VNS
